Answer:
<em>y = 4(0.75) or y = 3</em>
Step-by-step explanation:
The question is incomplete. Here is the complete question:
<em>The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.</em>
<em />
<em>Let the amount baking soda required for a whole cake be y.</em>
<em />
<em>If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;</em>
<em />
<em>1/4 sheet of cake = 0.75 teaspoon of soda</em>
<em>1 sheet of cake = y teaspoon of soda</em>
<em />
<em>cross multiply</em>
<em>1/4 * y = 1 * 0.75</em>
<em />
<em>y/4 = 0.75</em>
<em>multiply both sides by 4</em>
<em />
<em>y/4 * 4 = 0.75 * 4</em>
<em />
<em>y = 4(0.75)</em>
<em />
<em>y = 3 teaspoon of baking soda</em>

2x-10
Step-by-step explanation:
no time to explain
They've given me two categories of things: assessed values of properties, and the amounts of taxes paid. My ratios will then use these two categories. I will set up my ratios with the assessed valuation on top (because that's what I read first in the exercise), and I will use "v" to stand for the value that I need to find.
value
tax
:
70,000
1,100
=
v
1,400
tax
value
:
1,100
70,000
=
1,400
v
I'll use the shortcut method for solving, multiplying the 70,000 and the 1,400 in one direction, and then dividing by the 1,100 going in the other direction:
70,000 / 1,100 = v / 1,400; multiplying gives (70,000)(1,400); dividing gives v = [(70,000)(1,400)]/1,100
v
=
(
70,000
)
(
1,400
)
1,100
v=
1,100
(70,000)(1,400)
v
=
98,000,000
1,100
v=
1,100
98,000,000
v
=
89,090.9090909...
v=89,090.9090909...
Since the solution is a dollars-and-cents value, I must round the final answer to two decimal places; the "exact" form (whether repeating decimal or fraction) wouldn't make sense in this context. So my answer is: $ 89.090.91
I was not sure if the x in your equation was a multiplication sign or a variable
6/7x
-1 multiplied by 3/7x times -2
And when you multiply two negatives it equals a posible so the -2 and -1 turn into a positive
Answer: D
Step-by-step explanation:
(x-9)² = x-3
(x-9) (x-9)= x-3
x² - 9x-9x +81 = x-3
x² -18x+81 =x-3
x²-19x+84 =0
(x-12)(x-7)=0
x=12 or 7
